为什么这个函数不存储变量，为什么不验证名字？
由于某种原因它不起作用。
当我打开时，控制台中没有错误消息网站。
请帮忙，这很烦人，我已经为此苦苦挣扎了一段时间。
是否有一些错误消息导致我的 JavaScript 代码无法工作？

代码看起来不错，但从这段代码来看，我暗中指出您遇到了安全错误，可能是由于没有提供文件，并且在浏览器而不是 file:// 。如果您停止完成提交的代码，您可以看到正确的错误。
http[s]://请求违反了策略决定，或者源不是有效的方案/主机/端口元组（例如，如果源使用文件：或数据：方案，就会发生这种情况）。例如，用户可能将他们的浏览器配置为拒绝为指定源保留数据的权限。
